Preventive health platform Lucis has raised $20 million Series A, led by Singular, with participation from General Catalyst, Y Combinator, and angels including investors behind Runna, Céline Lazorthes (Resilience), and Manu Lecomte.
The round follows Lucis’s $8 million seed raised four months ago, bringing total funding to $28 million.
Founded in 2025 by Maxime Berthelot and Baptiste Debever, Lucis provides individuals with a comprehensive, data-driven view of their health.
The platform analyses more than 110 blood biomarkers across key systems, including metabolic health, hormones, cardiovascular risk, inflammation, and nutrient levels. These results feed into an AI-powered health companion app, alongside longitudinal data and medical context, to deliver personalised guidance spanning nutrition, supplementation, lifestyle changes and follow-up testing
. Recommendations are continuously refined as new data becomes available and are reviewed by physicians, helping users understand what actions to take, not just what the data shows.
